CHARLES SEYMOUR, OF DEFIANOE, OHIO, ASSIGNOR TO THE DEFIANCE MACHINEWORKS, OF SAME PLACE.

SHAPlNG-MACHINE.

SPECIFICATION forming part ef Letters Patent No. 619,092, dated February7, 1899.

Application filed September 30, 1898- SerialNo. 692,317. (No model.)

To all whom t may concern.-

Be it known that I, CHARLES SEYMOUR, of Deiiance, in the county efDefiance and State of Ohio, have invented a new and ImprovedShaping-Machine, of which the following is a full, clear, and exactdescription.

The invention relates te woodworking machinery; and its object is teprovide a new and improved shaping-machine more especially designed forperfectly, rapidly, and automatically rounding or smoothly shaping theouter portion of the handheld en D-handles intended for shovels, spades,forks, and other implements.

The invention consists of certain parts and details and combinations ofthe same, as will be fully described hereinafter and then peinted out inthe claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both the figures.

Figure l is a perspective view of the improvement, showing the handle inposition after the operation; and Fig. 2 is a plan view of the same withthe driving-gear omitted and the handle shown in positionat thebeginning of the operation.

The improved shapingmachine is provided with a table A, mounted en asuitable standard A' and carrying a pivot B for an oscillating carriageC, mounted to swing on top ef the table. The carriage C is adapted tosupport the handle D er other article te be treated, the said handleresting with its shank D' in a fork E, carried by the carriage, and thehandheld D2 of the said handle is engaged on opposite sides by theclamps F and F', of which the clamp F is rigidly secured te the carriageC, and the clamp F' is fulcrumed at F2 en the said carriage. A screw Gscrews in a nut C' formed en the carriage te engage the free end of thepivoted clamp F', se as te move the latter in rm contactwith one side ofthe handheld D2, whereby the latter is securely clamped in positionbetween the clamps F and F'.

The pivoted clamp F' is provided with a segmental slot F3, through whichpasses a bolt F4, attached te the carriage C, to properly guide theclamp F' in its oscillating movement. The screw G is provided with ahandwheel G', under the control of the operator, for readily turning thescrew up against the clamp F' for moving the latter inte engagement withthe handheld in order to secure the handle in place on the carriage andto release the said clamp F' when it is desired te remove the finishedhandle and replace the same by another to be treated.

On top ef the table A is secured a knife er cutter H, having asemicircular cutting edge H', against which is moved the outer portionof the handheld D2 upon oscillating the carriage, so as to round eff thesaid outer portion of the handheld, as will be readily understood byreference to Fig. l.

In order te impart an oscillating motion to the carriage C, I connectthe latter by a pitman I with a crank-disk J, secured on the upper endof a vertically-disposed shaft J', journaled in suitable bearingscarried en the under side of the table A. On the lower end of the shaftJ is secured a bevel gear-wheel K, in mesh with a bevel-pinion K',fastened te one end of a driving-shaft L, journaled en the standard A'and carrying a friction-Glu tch pulley N, connected by a belt withsuitable machinery for imparting a rotary motion to the said pulley. Alever O, under the control of the operator, serves to actuate thefriction-clutch for the friction-clutch pulley to rotate the shaft LWhenever it is desired to de se. New it is evident that when the shaft Lis rotated a rotary motion is transmitted by the pinion K' andgear-Wheel K to the shaft J', se that the crank-disk .I and pitman Icause an oscillation of the carriage C te move the handheld D2 againstthe knife-edge H', se as to give the desired shape to the outer portionof the handheld D2. On the return stroke of the carriage C the handheldD2 passes clear ef the knife H, and at this time the operator steps themachine by manipulating the hand-lever O, and then turns the hand-wheelG' to release the clamp F', so as te permit the operator te remove thefinished handle D and te place another to be treated inte the fork F.and between the clamps F and F'. The hand-wheel G is new turned in theopposite direction te ber of handles in a comparatively short time.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- Y In a shaping-machine,the combination with aframe or standard having a table at the top thereof, of a carriagemounted to rock horizontally on the table, jaws held by the carriage forclamping the Work thereon, a knife fixed to the table and engaged by thework as the table swings, a vertically-extending shaft mounted in thetable, a link connected with y the carriage and having crankedconnection with the shaft, and gearing located below the table andcarried by the frame or standard, such frame being connect-ed with thevertica11yextending shaft, to drive the same.
